What is the missing step in this proof

1 answer:

8 0

Ok the parralelogram is 25 units and I think the angle of BCD would be 53. I got this by subtracting 127 from 180 since that should give you the whole square. and I got teh units by adding the lines BC and AB... Hope this helped

(5 Points) all (1 – 3K) -396 0-374 0 -198 0 -187

Triss [41]

Answer:−3K−395,−374,−198,−187

Step-by-step explanation:

Remove parentheses.

1−3K−396,0−374,0−198,0−187

Simplify 1-3K-3961−3K−396 to -3K-395−3K−395.

−3K−395,0−374,0−198,0−187

Simplify 0-3740−374 to -374−374.

−3K−395,−374,0−198,0−187

Simplify 0-1980−198 to -198−198.

−3K−395,−374,−198,0−187

Simplify 0-1870−187 to -187−187.

−3K−395,−374,−198,−187

If (7²)x = 1 what is the vaule of x

IrinaVladis [17]

Answer:

x=4

Step-by-step explanation:

1 Add 11 to both sides.

2x=7+12x=7+1

2 Simplify 7+17+1 to 88.

2x=82x=8

3 Divide both sides by 22.

x=\frac{8}{2}x=

4 Simplify \frac{8}{2}

 to 44.

x=4x=4

cheek:

1 Let x=4x=4.

2\times 4-1=72×4−1=7

2 Simplify 2\times 42×4 to 88.

8-1=78−1=7

3 Simplify 8-18−1 to 77.

7=7 7=7

(or -3)

An amusement park ride rotates around a fixed axis such that the angular position of a point on the ride follows the equation: θ

pshichka [43]

I found a missing question online. What is the magnitude of the angular displacement of the ride in radians between times t=0 and t= t1?
We can imagine our ride traveling from the starting point A to some point B (at t=1s).
We can find the angle of both points, and when we subtract them we get angular displacement.
 $A: \theta(0)=a\\
B: \theta(1)=a+b(1)^2-c(1)^3=a+b-c$
Our angular displacement is:
 $\Delta\theta=\theta(1)-\theta(0)=a+b-c-a=b-c=0.85-0.035=0.815 rad$
